IMPROVEMENT IN CORN-PLANTERS.

Specification founing part of Letters Patent No. 25,5486, dated J unc26, 1860.

RhaVe. invented a new and Improved Corn- Planter; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the annexed drawings, making apart ofthis specication, in which- Figure l is a plan or top view of my invention. Fig. 2 is a vertical section of the same, taken in the line a? x,Fig. l. Fig. 8 is a detached view of a portion of the same.

Similar letters of reference indicate corresponding parts in the severalfigures. .y

The object of this invention is to obtain a corn-planting machine ofsimple construction, by which corn may be planted in check-rows withoutpreviously furrowing the ground.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A A represent a pair of thills, which are mounted on wheels B B', andare connected at their back parts by traverse-bars c b c, forming aframe to sustain the working parts of the machine. The wheel B has itsperiphery provided with teeth or projections a to prevent slipping, andto the axle C 0I' the wheels and adjoining wheel B a toothed wheel, (l,is placed.

To the front traverse-bar, a, a frame, D, is attached by joints orhinges e, and in this frame D a shait, f, is tted longitudinally, oneend of the shaft projecting beyond the thills, and 'having a wheel, g,on it, which wheel, when the seed-distributing device is in operation,gears into the wheel d on axle C. On the shaft j', and within the frameD, there is placed a cam, E. This is a double cam, or it is formed4 oftwo parts, h fi, which actuate different devices, the part h actuating aseedslide, F, through the medium of a lever, G, and .the other part,fz', actuating markers H through the medium of levers I and verticalsliding bars J.

l The part i of the cam E may be described as being formed of a cylinderwith longitudinal sections removed to form two prominent parts, jj, asshown clearly in Fig. 2, and the part 71.

' may be described as being a zigzag flange having a circumferentialposition on the part fi. The front end of the lever Gis forked, and thepart z' of the cam is tted and works within the fork, as shown in Fig.l.`

K K are seed-boxes on the back traversebar, c, of the thills, and overthe bottom of which boxes the seed-slide F works, the back part of leverG being attached to the slide F by means of a pin, lf, which is attachedto the slide F, and is fitted in a slot, Z, in the back end of thelever, as shown clearly in Fig. 1. The seed-slide F is perforated, or isprovided with seed-cells m, and works in the usual way, distributing theseed into hollowteeth or shares G G, the upper ends of 'which areattached to the under side ofthe bar c by joints c', as shown clearly inFig. 2. The teeth or shares G are connected to the frame D by rods a.

To the back ends of the thills A A a crossbar, L, is attached. rIhis barprojects at both ends beyond the sides of the thills A A, and each endofthe bar L is forked or divari cated to form bearings or guides forvertical rods M M, which may be made of spade form at their lower endsto form the markers H, as shown in Fig. 3.

To the upper end of each rod M the levers I are attached. These levershave their fulcra o in uprights O on the frame of the machine, and thefront ends of the levers I are connected to the bars J, which areslotted vertically, or may be described as being formed of two verticalparts, p p, between which the shaft f of the frame D passes. (See Fig.2.) The lower end of each bar J has a pin, q, attached, said pinsbearing against th e under. si dc of thepart of cam E.

To the front part of the frame D a chain, N, is attached, said chainpassing within reach of the drivers seat, which may be placed on theframe at any convenient point-on the center traverse-bar, b, forinstance.

. The operation is as follows: As the machine is drawn along, the frameD being -in a horizontal position, the shaft f will be rotated by thegearing d g, and the cam E will actuate the seed-slide F and one markerH, the latter dropping simultaneously with the corn and marking, as onerow of corn is planted, the spots for the hills in the succeeding row.As the machine passes along to plant the succeeding row of corn thedriver watches the spots made by the markers II during the planting ofthe previous row, and so manages the seed-distrib uting device that theseed will be dropped at said spots. This result is effected by raisingthe frame D, and thereby throwing the wheel g out of gear with the wheelel, so that the cam E may be turned backward or forward until it isbrought in right position to actuate the slide F at the proper time todrop the seed in the desired place, the machine remaining stationary, orthe machine may be kept moving and the frame D allowed to drop at theproper time to produce the desired result. W'hen the frame D is raised,the shares G are elevated above the ground. The machine, therefore,

may be readily moved from place to place.

I do not claim the markers H, when separately considered, for they havebeen previously used; nor do I claim. a zigzag cam for operating,through the medium of a lever, a reciprocating seed-slide; but

I do claim as new and desire to secure by T. S. MILLS.
